Purpose: To describe the clinical course of a patient with Acanthamoeba keratitis, who despite prompt treatment progressed to histopathology-confirmed Acanthamoeba retinitis and endophthalmitis.
Methods: Case report.
Results: A healthy 30-year-old male wearing soft contact lens was diagnosed with Acanthamoeba keratitis and treated medically and surgically over the course of 1 year with presumed resolution of the infection. Yet, his infection recurred with documented spread to sclerokeratitis, and overwhelming endophthalmitis. Concerns about extra-ocular spread prompted a therapeutic enucleation with histopathologic evidence of Acanthamoeba organisms throughout the globe.
Conclusion: This is a case of a severe recurrent Acanthamoeba infection presenting initially as keratitis, followed by sclerokeratitis and histolopathology-confirmed endophthalmitis. This case demonstrates that despite persistent medical and surgical intervention, eradication of organisms may not be possible.
Extra-corneal manifestations of Acanthamoeba keratitis are uncommon but may be sight-threatening. These manifestations include sclerokeratitis and rarely posterior segment involvement. We describe the clinical and histopathologic findings of a rare case of Acanthamoeba keratitis which progressed to infectious sclerokeratitis and endophthalmitis.
